Create a webapp which has two sections.
4+
5+
Section 1 : You can upload any valid pic(JPG/PNG), pdf or word doc only with limit 2MB.
6+
7+
Section 2 : Here you can see the listing of all your documents. (URL only)
8+
9+
10+
Technology stack :
11+
Spring MVC
12+
Hibernate
13+
MySQL : A table which consists all the generated S3 URLs
14+
AWS S3 : All the documents will be uploaded on this server and there is a specific public URL of it.
15+
Don't forget client and server side validation.
16+
Don't focus too much on UI part, simple bootstrap would be enough. Focus on functionality.
